What is Augmented Reality (AR)?
Augmented Reality bridges the virtual world and the real world by superimposing digital contexts into the real context. Elements are augmented by a computer-generated sensory input such as video, graphics, sound or GPS data. With this technology, information about the real world can now be interactive and digitally manipulable.

How does AR work?
With augmented reality, the user sees the real world but with superimposed digital contexts using devices such as a smartphone or wearable device which contains software that recognizes an image and helps displays this onto an object. In essence, augmented reality enhances the real world with artificial images, videos or sound (Virtual Reality Site, 2015).
Applications can use one of two approaches: Marker-based and Location-based
Marker-based approach involves software which recognizes a particular pattern, such as a barcode or symbol, when a camera is pointing at it. An overlaying digital image then imposes when the camera is pointing at it.
Location-based applications uses GPS to record a position in the world and provide data that is relevant to that location. For example, naming the lakes around you, finding your way around a city, remembering a particular restaurant or where you parked your car or learning about the constellations when looking up at the stars.
